OPTIMIZATION OF DRYING TRAJECTORIES TO RETAIN NUTRITIONAL COMPONENTS IN BROCCOLI
Heat load during drying results in degradation of bioactive compounds,while drying under mild conditions ends in low energy efficiency.To combine retention of bioactive compounds in combination with high energy efficiency,optimal drying trajectories are calculated for the control variables air flow rate and temperature.For drying of broccoli the considered bioactive compounds are vitamin C and glucosinolates.Optimal drying trajectories plotted in state diagrams with degradation and drying rates,explain the calculated drying strategies.The drying strategies allow for halving the energy consumption and a significant increase of vitamin C content.
